Hey! Nice to see you :) There's another installation error with Poetry at #6278 — sounds like we need to dedicate some attention to compatibility with it. |

Hm. Our published wheel explicitly includes the (some content omitted) [[package]]
name = "prefect"
version = "2.0.3"
[package.dependencies]
sqlalchemy = {version = ">=1.4.20,<1.4.33 || >1.4.33", extras = ["asyncio"]}
[[package]]
name = "sqlalchemy"
[package.dependencies]
greenlet = {version = "!=0.4.17", markers = "python_version >= \"3\" and (platform_machine == \"aarch64\" or platform_machine == \"ppc64le\" or platform_machine == \"x86_64\" or platform_machine == \"amd64\" or platform_machine == \"AMD64\" or platform_machine == \"win32\" or platform_machine == \"WIN32\")"}
[package.extras]
asyncio = ["greenlet (!=0.4.17)"]and If I created a new poetry shell for isolation, I could reproduce your issue. Interestingly, but if I run this command in my working conda environment, it does: This seems like a poetry bug. |

Thanks for looking into this! Awesome to see you here. That matches what I'm seeing on my Poetry environment too. Does indeed seem like a Poetry bug. |

First check
Bug summary
Installing Prefect on an M1 with Poetry skips the SQLAlchemy dependency greenlet.
It seems like this is a known issue with SQLAlchemy + Greenlet (see context) – and explicitly adding
sqlalchemy[asyncio]as is done in Prefect's requirements.txt fixes with pip – but a Poetry install of Prefect on an M1 still fails.Reproduction
On an M1 machine:
poetry new test-projectpoetry add prefectIn a new file, pipeline.py:
poetry run python3 pipeline.pyError
Versions
Additional context
After manually adding greenlet (
poetry add greenlet) this works fine! It looks like Poetry isn't picking up the extra insqlalchemy[asyncio].This might be outside of fair game for a Prefect issue, because it's an issue with a Prefect dependency – and only while using Poetry. Opening this issue because @madkinsz introduced me to Poetry :)
There are closed issues on SQLAlchemy (sqlalchemy/sqlalchemy#7714) and greenlet (python-greenlet/greenlet#234).
